(v) Known to the other Party lawfully from a source other than the first Party as can be proved by the other Party by a written document; or

(vi) Disclosed as required by operation of law.

10.3 Each Party shall keep in strict confidence any and all Proprietary Information and not directly or indirectly disclose it or make it available for any purpose to any person or entity other than its personnel who legitimately need to have the Proprietary Information for purposes directly related and necessary to its performance under this Agreement. Each Party shall use such information only for the purpose of performing hereunder and shall reproduce such Proprietary Information only to extent necessary for such purpose. Each Party represents and warrants that personnel employed by each Party that are working on this project have entered into general Confidentiality Agreements with their respective employers.

10.4 The Parties agree that in the event of any breach by one Party of any of its obligations hereunder, the other Party will suffer irreparable harm and that monetary damages will be inadequate to compensate such Party for such breach. Accordingly, each Party agrees that the other will, in addition to any other remedies available to it at law or in equity, be entitled to preliminary and permanent injunctive relief to enforce any such breach of the terms of this Section 10.

10.5 All Proprietary Information, including copies thereof, shall remain the property of originator and, except as specified in this Agreement, shall be immediately returned to originator (and not used for any purposes) upon request therefor or upon any termination of this Agreement, provided that one copy may be retained for legal purposes only. Each Party further agrees that all of its obligations undertaken pursuant to this Section 10 shall survive and continue after termination of this Agreement for any reason.

10.6 Trademarks. Nothing in this Agreement grants to either Party the right to use or display the names, trademarks, trade dress, trade names, logos or service marks of the other Party, except to identify the Instruments and associated services of the other Party to the extent obligations are undertaken pursuant to this Agreement. Except in the case of correspondence and proposals issued in the ordinary course of business, each Party agrees to submit to the Party for written prepublication approval, any materials which may use or display any name, trademark, trade name, logo or service mark of the other Party. Notwithstanding the foregoing, nothing contained in this Agreement shall affect either Party’s rights to use, including but not limited to attempt to register or file any such trademarks in any jurisdiction, any trademarks, service marks or proprietary words or symbols of the other Party to properly identify the goods or services of such other Party to the extent otherwise permitted by applicable law or by written agreement between Parties.

The foregoing limited license applies only with respect to the Instruments as described in the PDR and PSD and not to any other products (including successor products) and does not grant QTX any rights to (1) any source code of STRATEC, (2) to provide any direct competitor of STRATEC with any of STRATEC’s proprietary software libraries or STRATEC Intellectual Property Rights, or (3) to make any improvements, modifications or derivatives. Any improvements, modifications or derivatives conceived by QTX or any third party shall be solely owned by STRATEC and QTX hereby agrees to transfer or have transferred such rights to STRATEC.

13.4 Noninterference. Both Parties represent and warrant that no provision of this Agreement is in any way in conflict with or impairs performance of any present contractual obligation to any third party and neither Party nor any persons employed by a Party or who assists Party in the implementation of this Agreement will assume any obligation or restriction which will conflict with or prevent them from performing any of the services called for by this Agreement.

13.5 Assignments, Succession and Waivers. Except where the assignee is a successor in business or an Affiliate, this Agreement or any part thereof shall not be assignable, and any attempted assignment shall be null and void, without first obtaining the express written consent of the other Party, provided, however, that either Party may assign this Agreement to an Affiliate or to a purchaser of substantially all of the assets of the business to which this Agreement relates without the prior consent of the other Party. This Agreement shall be binding upon and shall inure to the benefit of the Parties, their successors and permitted assignees. No express waiver or any prior breach of this Agreement shall constitute a waiver of any subsequent breach hereof and no waiver shall be implied.

13.6 Force Majeure. Neither Party shall be liable in damages for, nor shall this Agreement be terminable or cancelable by reason of any delay or default in such Party’s performance hereunder if such default or delay is caused by events beyond such Party’s reasonable control including, but not limited to, acts of God, acts of terrorism or other attacks launched as acts of war or, regulation or law or other action of any government or agency thereof, insurrection, civil commotion, destruction of production facilities or materials by earthquake, fire, flood or storm, labor disturbances, or epidemic. Each Party agrees to use its best efforts to resume its performance hereunder if such performance is delayed or interrupted by reason of such forces majeure as listed above.

13.7 Integration. This Agreement and the Development Agreement are intended to be executed concurrently and express the entire understanding between QTX and STRATEC with respect to the subject matter addressed and merge all prior oral discussions or written correspondence between them. This Agreement and the Development Agreement shall be read and interpreted together. No notification, extension, or waiver of this Agreement or any provision hereof shall be binding unless agreed to in writing by the Parties.

13.8 Publication. Neither Party shall disclose the existence of this Agreement or the contents thereof to the public or any third parties without the prior written consent of the other Party. However, either Party shall have the right to disclose information, including, if applicable, the Agreement or the contents thereof, only as necessary to meet its legal obligations. Unless required by law, the Parties hereto shall use their best effort to reach agreement on the contents and the scheduling of the public disclosure of any such information.

13.9 Governing Law. The present Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, U.S.A. The Parties agree that the United Nations Convention on the International Sale of Goods shall not apply to the transactions contemplated under this Agreement. The Parties shall first attempt to resolve any dispute arising out of or relating to this Agreement in good faith through an amicable settlement.

13.10 Legal Counsel. Each Party is a sophisticated business entity which has involved legal counsel of its own choosing in the drafting, negotiating and concluding of this Agreement and any presumption in statutory or common law against the drafter of any particular provision herein, or against the drafter of this Agreement as a whole, shall be of no effect whatsoever and each Party covenants to, and shall, refrain from asserting or relying upon any such presumption.

13.11 Severability. If any provision of this Agreement is held unenforceable or in conflict with the law of any jurisdiction, it is the intention of the Parties that the validity and enforceability of the remaining provisions hereof shall not be affected by such holding.

13.12 Non-Waiver. Failure of either Party hereto to insist on strict performance shall not constitute a waiver of any of the provisions of this Agreement or waiver of any future default of STRATEC.

13.13 Dispute Resolution; Arbitration.

a. In the event that any dispute, controversy or claim between the Parties arising out of, relating to or in connection with this Agreement, including, without limitation, any dispute regarding validity or termination, or performance or breach thereof, is not resolved within fifteen (15) days by the negotiations of the Steering Committee, either Party may refer such dispute, controversy or claim to the Chief Executive Officer of STRATEC and the Chief Executive Officer of QTX, or their designee, who shall, as soon as practicable, attempt in good faith to resolve the dispute, controversy or claim.

b. In the event the Parties’ Chief Executive Officers (or designees) are not able to resolve such dispute within fifteen (15) days, either Party may at any time after such thirty (30) day period submit such dispute to be finally resolved by arbitration administered in accordance with the Commercial Arbitration Rules of the American Arbitration Association pursuant to its Expedited Procedures in effect at the time, except as they may be modified herein or by agreement of the Parties. The arbitration will be held in San Francisco, California, before a single arbitrator knowledgeable in diagnostic device development and supply arrangements. The arbitration must commence within fifteen (15) days of the date on which a written demand for arbitration is filed by either Party. Prompt resolution of any dispute is important to both Parties, and the Parties agree that the arbitration of any dispute shall be conducted expeditiously. The arbitrator is instructed and directed to assume case management initiative and control over the arbitration process (including, without limitation, scheduling of events, pre-hearing discovery and activities, and the conduct of the hearing), in order to complete the arbitration as expeditiously as is reasonably practical for obtaining a just resolution of the dispute. The arbitrator will have the power to order the production of documents by each Party and any third party witnesses; however, the arbitrator will not have the power to order the taking of depositions, the answering of interrogatories or the responses to requests for admission. The arbitrator will not have power to award damages that are specifically excluded under this Agreement, and each Party hereby irrevocably waives any claim to such damages. The Parties covenant and agree that they will participate in the arbitration in good faith and that they will share equally its costs, except as otherwise provided below. The arbitrator may in his or her discretion assess costs and expenses (including the reasonable legal fees and expenses of the prevailing Party) against any Party to a proceeding. Any Party refusing to comply with an order of the arbitrators will be liable for costs and expenses, including attorneys’ fees, incurred by the other Party in enforcing the award.

c. The arbitration proceedings shall be conducted in the English language. All submissions to the arbitrator and any ruling or award shall be made in English and be treated as Confidential

Information. Any award of the arbitrator shall be final and binding upon the Parties, their successors and permitted assigns and all other Parties to this Agreement, their successors and permitted assigns. The Arbitration Parties waive to the fullest extent permitted by law any rights to appeal to, or to seek review of such award by, any court or tribunal. Judgment on the award may be entered in any court of competent jurisdiction. Notwithstanding the foregoing to the contrary, in the case of temporary or preliminary injunctive relief related to the ownership or dispute directly related to Intellectual Property Rights or Confidential Information, any Party may proceed in court without prior arbitration for the purpose of avoiding immediate and irreparable harm.

13.14 Headings. All Sections and paragraph captions or titles are intended only for reference purposes and are without contractual significance or effect.

13.15 Survivability. Sections 1; 3.4; 3.5; 3.6; 6.3 (for Instruments properly shipped under this Agreement prior to termination or expiration); 6.4; 6.5; 6.6; 6.7; 9, 10; 11; 12 and 13 shall survive termination of this Agreement regardless of reason for termination.

13.16 Injunctive Relief. The Parties agree that injunctive relief is appropriate in enforcing the confidentiality provisions of this Agreement. In the event of any such action to construe this provision, the prevailing Party will be entitled to recover, in addition to any charges fixed by the court, its costs and expenses of suit, including reasonable attorney’s fees.

13.17 Counterparts. This Agreement may be executed in one or more copies, each of which will be deemed to be an original, but all of which together will constitute one and the same instrument; however, this Agreement shall have no force or effect until executed by both Parties.

IN WITNESS WHEREOF, the Parties hereto have executed this Agreement as of the Effective Date:
